Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496200, here are decompositions:

59 + 31496141 = 31496200
101 + 31496099 = 31496200
173 + 31496027 = 31496200
251 + 31495949 = 31496200
353 + 31495847 = 31496200
443 + 31495757 = 31496200
467 + 31495733 = 31496200
509 + 31495691 = 31496200

Showing the first eight; more decompositions exist.
